rat disection

The purpose of the rat dissection is to do a comparative examination between human systems, the components that make up the systems, the organs, how they’re organized and how do they compare to the rat

For this demo i am disecting a rat to see its major organs i will observe its hart,stomach,liver,and its intestens. it helps me understand how its major organs operate.

this is the rat before the dissection

cut from the neck down dont make deep cuts because you might puncture its organs

you have to cut in four one forth to get a good view of the rats organs her you can see part of the liver and the stomach

my scalpel is pointing to the hart of the rat but it is being blocked by the throught of the rat

in this picture you can see the rat has two livers and the neck was cut to see the hart
